Fate of "Space-like singularities" in Matrix Model
Sumit R. Das, Shaun D. Hampton, Sinong Liu +1
A class of time dependent backgrounds in two dimensional String Theory leads to superluminal Liouville walls on the worldsheet. In the dual double scaled matrix model these b…

Superluminal Liouville walls in 2d String Theory and space-like singularities
Sumit R. Das, Shaun D. Hampton, Sinong Liu
An interesting class of time dependent backgrounds in dimensional string theory involves worldsheet Liouville walls which move in (target space) time. When a parameter in suc…
